Thread-In Receptacles for Quick-Release Pins
Use a screwdriver to install these receptacles in a threaded hole. Use them to secure quick-release pins when you can't drill a through hole. They're made of 18-8 stainless steel for a balance of strength and corrosion resistance, and passivated for added protection against corrosion and oxidation.

Threaded Spring-Loaded Guide Pins
Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications. A sealed top prevents debris from getting inside and making them seize up. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

Threaded Plug Gauges with Calibration Certificate
These gauges come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They allow you to inspect internal threads on parts. All have a go gauge on one end and a no-go gauge on the other end. A taperlock handle lets you quickly replace worn gauges.
Check the minimum internal thread size with the go gauge end, and check the maximum internal thread size with the no-go gauge end. A part is within tolerance if it’s easy to thread the go gauge into the part but difficult to thread the no-go gauge more than two turns.
Threads have different classes of fit. Thread fit designates the tightness or looseness of mating threads. For example, inch threads with a 3B fit have tighter tolerances than threads with a 2B fit.
